Cute little feel-good game that has some zen-like vibe to it in its serenity. The core mechanics work well, have to point out the nice tutorial at the start that was informative but stayed to the point, kudos on that! Played for some 15 minutes upgrading stuff, then ran out of food. Some pointers:
UI scales weird when fullscreen, also the upgrade window blocks the amount of money you have when open.
It's rather easy to get lost with no clear way to see where you have been to - perhaps a minimap or something?
